With Laravel you can use:
使用 Laravel，您可以使用：
$path = public_path().'/images';
File::isDirectory($path) or File::makeDirectory($path, 0777, true, true);
By the way, you can also put subfolders as argument in a Laravel path helper function, just like this:
顺便说一句，您还可以将子文件夹作为参数放在 Laravel 路径辅助函数中，就像这样：
$path = public_path('images/');

The recommended way is to use
推荐的方法是使用
if (!File::exists($path))
{
}
See the source code
查看源代码
If you look at the code, it's calling file_exists()
如果您查看代码，它正在调用 file_exists()

Way -1 :
方式-1：
if(!is_dir($backupLoc)) {
mkdir($backupLoc, 0755, true);
}
Way -2 :
方式-2：
if (!file_exists($backupLoc)) {
mkdir($backupLoc, 0755, true);
}
Way -3 :
方式-3：
if(!File::exists($backupLoc)) {
File::makeDirectory($backupLoc, 0755, true, true);
}
Do not forget to use use Illuminate\Support\Facades\File;
不要忘记使用 Illuminate\Support\Facades\File;
Way -4 :
方式-4：
if(!File::exists($backupLoc)) {
Storage::makeDirectory($backupLoc, 0755, true, true);
}
In this way you have to put the configuration first in config folder filesystems.php . [Not recommended unless you are using external disks]
通过这种方式，您必须首先将配置放在 config 文件夹 filesystems.php 中。[除非您使用外部磁盘，否则不推荐使用]

In Laravel 5.x/6 you can do it with Storage Facade:
在 Laravel 5.x/6 中，您可以使用Storage Facade 来实现：
use Illuminate\Support\Facades\Storage;
$path = "path/to/folder/";
if(!Storage::exists($path)){
Storage::makeDirectory($path);
}

I normally create random folders inside the images for each file this helps a bit in encrypting urls and thus public will find it hardr to view your files by simply typing the url to your directory.
我通常在每个文件的图像内创建随机文件夹，这有助于加密 url，因此公众将发现只需将 url 输入到您的目录中就很难查看您的文件。
// Check if Logo is uploaded and file in random folder name -
if (Input::hasFile('whatever_logo'))
{
$destinationPath = 'uploads/images/' .str_random(8).'/';
$file = Input::file('whatever_logo');
$filename = $file->getClientOriginalName();
$file->move($destinationPath, $filename);
$savedPath = $destinationPath . $filename;
$this->whatever->logo = $savedPath;
$this->whatever->save();
}
// otherwise NULL the logo field in DB table.
else
{
$this->whatever->logo = NULL;
$this->whatever->save();
}
